In biological taxonomy, race is an informal rank in the taxonomic hierarchy for which various definitions exist. Sometimes it is used to denote a level below that of subspecies, while at other times it is used as a synonym for subspecies. [1] It has been used as a higher rank than strain, with several strains making up one race.
tinman, or tin is an Nk2-homeobox containing transcription factor first isolated in Drosophila flies. The human homolog is the Nkx2-5 gene. tinman is expressed in the precardiac mesoderm and is responsible for the differentiation, proliferation, and specification of cardiac progenitor cells.
[5] [6] The division of humankind into biologically separate groups, along with the assignment of particular physical and mental characteristics to these groups through constructing and applying corresponding explanatory models, is referred to as racialism, racial realism, race realism, or race science by those who support these ideas.
Researchers have investigated the relationship between race and genetics as part of efforts to understand how biology may or may not contribute to human racial categorization. Today, the consensus among scientists is that race is a social construct , and that using it as a proxy for genetic differences among populations is misleading.
A Troublesome Inheritance: Genes, Race and Human History is a 2014 book by Nicholas Wade, a British writer, journalist, and former science and health editor for The New York Times.
Race is a categorization of humans based on shared physical or social qualities into groups generally viewed as distinct within a given society. [1] The term came into common usage during the 16th century, when it was used to refer to groups of various kinds, including those characterized by close kinship relations. [2]
"Human Genetic Diversity: Lewontin's Fallacy" is a 2003 paper by A. W. F. Edwards in the journal BioEssays. [1] He criticises an argument first made in Richard Lewontin's 1972 article "The Apportionment of Human Diversity", that the practice of dividing humanity into races is taxonomically invalid because any given individual will often have more in common genetically with members of other ...
The Mismeasure of Man is a 1981 book by paleontologist Stephen Jay Gould.The book is both a history and critique of the statistical methods and cultural motivations underlying biological determinism, the belief that "the social and economic differences between human groups—primarily races, classes, and sexes—arise from inherited, inborn distinctions and that society, in this sense, is an ...
